Abstract

L'invention est constituée par une antenne radio haute fréquence non directive et par une méthode connexe, la fréquence de travail de cette antenne étant d'environ 1,8 gigahertz. L'antenne de l'invention comporte un premier élément à enroulement hélicoïdal d'un quart de longueur d'onde supporté à l'extrémité proximale d'un fouet non conducteur et connecté aux circuits radio de l'émetteur-récepteur radio et couple le premier élément à ces circuits radio. Le premier élément de l'antenne étant monté à l'extrémité distale du fouet non conducteur, l'occultation résultant du positionnement de l'émetteur-récepteur radio à proximité de l'utilisateur devrait être moins nuisible au bon fonctionnement de l'émetteur-récepteur.
